Description
Technical field
The utility model relates to the field of medical instrument technology, specifically a kind of fine-tuning haemostatic clamp.
Background technique
Haemostatic clamp is used for surgical operation, and in the course of surgery, doctor clamps bleeding part with haemostatic clamp to stop blooding.It is existing
Haemostatic clamp includes two claw beams of pivot joint, and claw beam is equipped with hand-held part and caliper, and hand-held part is equipped with the finger for being inserted into finger
Circle uses the thumb of Shi doctor and index finger to be inserted into two fingers respectively and encloses, and passes through finger opening and closing band moving caliper opening and closing.In two hand-held parts
Inside corresponding position is equipped with the occlusion portion being mutually twisted, and occlusion portion is equipped with tooth engaged, and occlusion portion makes haemostatic clamp be able to maintain folder
Tight position, doctor do not need the clamping force for continuing to keep haemostatic clamp with finger.But carry out band moving caliper opening and closing by finger opening and closing
Holding causes clamping force excessive and causes patient injury very much.
Application No. is 201620227673.5 utility model patents to disclose a kind of orthopaedics haemostatic clamp, including passes through hinge
The lower end of the left clamp arm and right clamp arm of connection, left clamp arm and right clamp arm is connect with a handle respectively, referring to the patent document
The 0022nd section and 0023 section of specification, the junction of right clamp arm and handle is equipped with left stud, and the center of left stud is equipped with and left spiral shell
The coaxial column slot of column with a top there is the clamping device of traveller to connect by column slot, and traveller is slidably inserted into column slot, is stung
The external process of component has screw thread, and passes through adjusting nut for clamping device and left Stud connection, the junction of right clamp arm and handle
Equipped with right protrusion, right protrusion and clamping device patho-occlusion.When needing to be finely adjusted the chucking power of jaw, by right protrusion
With clamping device patho-occlusion, rotating adjusting nut, by clamping device and left Stud connection, adjustable range.The orthopaedics haemostatic clamp exists
Following disadvantage: (1) general both hands carry out different operations to doctor respectively during operation, for example both hands hold haemostatic clamp, the right hand
Haemostatic clamp for clamping blutpunkte, for the haemostatic clamp of left hand for clamping hemostatic cotton or left hand syringes, the right hand holds hemostasis
Both hands are needed to operate when clamping, and being finely adjusted using the orthopaedics haemostatic clamp, and cumbersome, this can reduce operation effect of doctor
Rate；(2) rotation adjusting nut may still be exerted oneself excessive due to doctor and cause clamping force excessive；(3) the flexible side of clamping device
To for along column slot direction, as straight line, and the direction of motion of right protrusion is camber line, therefore can not make left clamp arm and right clamp arm phase
To movement.
Utility model content
Purpose of the utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of fine-tuning haemostatic clamp, make
Doctor singlehanded can be finely adjusted the clamping force of fine-tuning haemostatic clamp and lock to its clamped position.
Technical problem to be solved in the utility model is realized using following technical scheme: a kind of fine-tuning haemostatic clamp,
Including fixed tong arm, movable tong arm, micro-adjusting mechanism and retaining mechanism；Handle, the adjustable clamp are installed on the fixed tong arm
Arm and fixed tong arm pivot joint；The micro-adjusting mechanism includes shaft, knob, damping arm, driving gear and driven gear；The shaft
It is mounted on fixed tong arm, the knob is fixedly connected with shaft；The periphery of the shaft is equipped with damping groove, the damping
Arm be mounted on fixed tong arm and its end and damping matching grooves；The driving gear is fixedly mounted in shaft, described
Driven gear is fixedly connected and coaxial with the drive-connecting shaft of movable tong arm with movable tong arm；The retaining mechanism includes locking plate, silk
Thick stick, guide post and lock sheet, the locking plate are fixedly connected with shaft, and the lead screw and guide post are installed in fixed tong arm
On, the lock sheet is slidably connected with guide post and connect with threads of lead screw, and the lock sheet is corresponding with the position of locking plate, institute
The end for stating lead screw is equipped with locking knob.
The technical solution of the utility model is also: being deceleration transmission between the driving gear and driven gear.Using this
Technical solution prevents from causing movable tong arm movement excessive because doctor's movement is excessive.
The technical solution of the utility model is also: the damping arm is equipped with two and is symmetricly set on the two sides of shaft.
The utility model additionally provides the application method of above-mentioned fine-tuning haemostatic clamp, comprising the following steps:
A, one hand holds handle, and fine-tuning haemostatic clamp is moved to bleed site；
B, with thumb rubbing knob, shaft rotates and passes through driving gear and driven gear drive activity tong arm is relatively fixed
Tong arm rotation, until fixed tong arm and movable tong arm clamp bleed site, end of damping arm is sequentially embedded resistance during this
In Buddhist nun's groove；
C, with thumb rubbing locking knob, lock sheet moves closer to locking plate under the action of lead screw, when lock sheet and lock
It, can not turning knob when tight disk contact.
Compared with the existing technology, when having the beneficial effect that (1) thumb rubbing knob of the fine-tuning haemostatic clamp of the utility model,
The end of damping arm is sequentially embedded in damping groove, so that the end of damping arm is left damping groove every time and is required one relatively
Big power, therefore can prevent doctor from causing clamping force excessive due to exerting oneself excessive, realize the micro- of fine-tuning haemostatic clamp clamping force
It adjusts；(2) clamped position of fine-tuning haemostatic clamp can be locked by retaining mechanism, doctor need not persistently apply fine-tuning haemostatic clamp
The clamped position of reinforcing, fine-tuning haemostatic clamp will not change because of touching patient body tissue；(3) doctor's one hand can be real
The fine tuning of existing fine-tuning haemostatic clamp locks and unlocks, and easy to operate, improves procedure efficiency.
